Chêne de Louis XIV (Buc) walks

This is the third stage of the GR® 11 Grand Tour of Île-de-France. It continues through the Yvelines, between Saint-Cyr station and Villiers-Neauphle-Pontchartrain station. This stage completes the 'radial' part of the GR® starting from Paris and joins the circular loop that circles the region from Villiers-Saint-Frédéric. The route passes through increasingly large wooded areas as you approach the countryside.

A route from station to station, through the woods and with some elevation gain. Walking or jogging.

An easy hike from Viroflay-Rive Gauche station to Chaville-Rive Gauche station. The town is never far away, but the forest remains a haven of peace and greenery. You can visit several places of interest, see some beautiful landscapes and get some fresh air!

This is the upstream section of this series of three walks dedicated to the Bièvre. A very pleasant route along the river and its ponds, in a setting that is mostly bucolic. A walk from station to station, the length of which can be adapted according to conditions or preference.

The Bièvre Valley is undoubtedly one of the best places for hiking in the region. Indeed, in summer it is a succession of ponds and lush green landscapes. This hike takes you through the most interesting part of the valley, featuring a succession of five remarkable ponds. You can then round off your day with a visit to Versailles, adding a touch of history to the route.

A hike from station to station, yo-yoing between the Yvette valley and the Saclay plateau, with a few fairly steep hills. After a mostly wooded route with some elevation, you cross Gif-sur-Yvette and then walk along a wetland area framed by two rivers. You climb back up onto the plateau, near the Paris-Saclay University campus. After visiting the old Troche quarry and walking along the edge of the plateau, you descend back into the valley.

A south-north crossing offering a very varied route. Sections through the forest alternate with stretches across fields. Water features are plentiful, with several rivers—the Yvette, the Marette and the Bièvre—and the Étangs de Montbrond set in their lush green surroundings. (Warning) The route is cut off at the point (12) due to works on Metro Line 18 (as of March 2026). A diversion is under consideration. Please refrain from undertaking this hike until further notice.
